01 / WHAT IT BUILT
What the company did
Complete Solar, founded in 2010 by Will Anderson, was a U.S. residential solar platform delivering industry-leading solar services through a digital platform for sales and installation with fast speed-to-install, plus monitoring of energy consumption and performance. It operated via a vast network of local installers and product specialists across the U.S., building a leader's reputation for customer satisfaction. The company did not fail - in November 2022 it merged with solar technology company Solaria to form Complete Solaria, which went public via SPAC (Nasdaq: CSLR) in July 2023, later acquired SunPower's assets for $45-46 million in August 2024, and rebranded as SunPower in April 2025.
